See the picture. 5-2-3 Selecting of the short and long pressing plate

1) When the thickness of workpiece is below 100mm, user could only select the long pressing plate for the short and long piece, but the short piece must be fed in continuously. 2) When the thickness of workpiece is excess 100mm, ripping long and thick piece will bring much sawdust. For guaranteeing the quality of saw ripping and protecting saw blade from being damaged, user must select the short pressing plate.

The pressing plate must use tough and complete solid woods or solid wood joint board and be made according to the size below.

5.3 Preparation of the saw blades

Note: Firstly, dismount the auxiliary support (See Ist part of IX.)

There are two methods to install or replace the saw blades with the sleeve:(Note: this machine can be installed 4 to 12 saw blades, when use the biggest saw blade to work the max. thickness work-piece, only you can use 4 saw blades. When use the small saw blade to work more thin work-piece, you can add or reduce the quantity of saw blade according to the working material quality.

5-3-1 While the sleeve set is not locked on the saw spindle: (1). Erect the sleeve on a table and install proper spacers and saw blades to it according to the working requirements. Before install the spacers and blades, make sure the edge of the spacers and the clamping point of saw blades are clean. Make sure all saw blades have identical diameter and teeth direction (See figure below). Then lock the sleeve nut firmly.

(2). Clean the contact area of the sleeve and the saw spindle, the bore of the sleeve and the saw spindle surface by clean cloth. Make sure no stains, chips or dust left. Otherwise, the saw blades may wobble and vibrate and affect the working accuracy seriously. (3). Turn the fixing pin of the saw spindle elevating handler and fit it into the place of LOOSE to loose the handler. Rotate the saw spindle elevating handler clockwise to lift the saw spindle to the limit. Then turn the fixing pin and fit it into the closest hole to fix the spindle at the highest position. Push the Pressing rollers fall button to lower down the pressing rollers case until there is enough space to fit the sleeve set to the saw spindle.

(4) Make sure the groove of the sleeve (A) firmly fit into the key at the end of the saw spindle (B) while installing the sleeve to the spindle.

(5). Use the following three special spanners to lock the sleeve nut and the saw spindle nut respectively.

5-3-2 While the sleeve set is locked on the saw spindle:

If the saw blades is stuck in the pressing plate, operators must lift the saw spindle and lower down the pressing plate seat to separate the saw blades and the pressing plate. (1). Separate the saw blades and pressing plate according to the third step of the first condition. Then loosen the saw spindle nut and sleeve nut and dismount the saw blades and spacers by applying saw spindle nut spanner, sleeve nut spanner and the saw spindle stuck spanner. (2). Replace the saw blades and spacers according to working requirements. Make sure the edge of the spacers and the clamping point of saw blades are clean. Make sure all saw blades have identical diameter and teeth direction. (3). Lock the sleeve nut and the spindle nut respectively according to the fifth step of the first condition.

5-4. Check the safety devices (1). Close the saw spindle case door. Check and make sure the safety switch of the door and handler is in the correct position. Check and make sure the anti-kickback fingers falls in a row to the direction of the chain blocks and could not be lifted easily.

(2). Make sure the power is ON and the emergency stop button rests.

5-5. Saw spindle positioning

Note: Firstly, release the auxiliary support (See Ist part of IX.)

Make sure the pressing plate and the saw blades sleeve set have been installed correctly. Then start the saw spindle and slowly rotate the saw spindle elevating handler counterclockwise to lower down the saw spindle, until the saw blades locating meter indicates the correct diameter of the saw blades (for example, if the diameter of the saw blades is 12’’, make adjustments until the meter indicates 12’’). After adjustment, make sure the fixing pin has been locked in the closest hole. After adjustment, reset the lock pin to lock the saw spindle.

5-6. Adjustment of the pressing rollers Push the Pressing rollers lift button or the Pressing rollers fall button and hold it to lower down or lift the pressing rollers, until the value of the reference meter is about 1-2 mm less than the thickness of the work pieces. If the pressing rollers fall too lower, wood pieces will cause the chain seriously worn even broken. For example, assuming the thickness of the work pieces is 100mm, adjust the height of pressing rollers to be 99.5-100.5mm. ( In case the pieces are not regular in thickness, please first lift the pressing rollers to 110mm and then lower down to 99.5-100.5 mm, to prevent the bolt of pressing plate breaking.

5-7. Adjustment of the in-feed fence The fence is positioned by the handler. It should be placed with space from the first saw blade. The space depends on the straightness of the edge of the work pieces. The more rough is the edge of pieces, the more space should be left.

5-8. Adjustment of auxiliary feeding pressing-rollers

This machine is equipped with auxiliary feed-in and feed-out device, to help the transportation of work pieces. After starting the saw spindle and feeding motor, turn the pressure feed roller switch on the operation button panel to the position ON. When the machine check out wood piece(the thickness of the work pieces must be more than 50 mm) at the feed entrance, the pneumatic hold-down mechanism will carry the top pressing roller down to press wood piece to help bottom auto roller feeding. When wood piece leave feed entrance, the pneumatic hold-down mechanism will auto rise back for next feeding. In order to shorten the back distance of pneumatic hold-down mechanism, adjust the two limit screws of two sides of the pneumatic hold-down mechanism (adjust to keep the same height of the two as far as possible). The adjustment make sure the height between top pressing roller and wood piece is about 10mm when the pneumatic hold-down mechanism back. After adjustment, tighten the locknuts firmly.

5-9. Starting the saw blades Press down the Saw spindle start button to start the saw blades.

5-10. Starting the feeding chain Press down the Feeding chain start button to start the feeding chain. Adjust the speed change knob to get a desired feeding speed. The feeding speed depends on the material, thickness, and finish requirements of the work pieces, sharpness and quantity of saw blades.

5-11. Feeding in (1). To reach the most accurate lengthwise straightness of pieces, please try to guarantee the pieces are in identical thickness(the thickness different of work pieces in 5mm), without bend or excessive distortion. The thickness of work pieces should not exceed 170 mm. (2). To guarantee the pressing plate could fully press the pieces, the length of work piece should not be shorter than 740 mm. (3). Place the work piece on the work table and press it to the fence firmly. Then push the work piece into the chain blocks and the pressing rollers for ripping. Once the work piece enter the machine, operators should release hands immediately. Even if the work piece does not enter in a straight line, the operator should never attempt to push the work piece to a straight line. (4). Keep checking the readout of Ampere meter (380V, 75kw, 140A) all the time to learn the load of the saw spindle motor and turn the Feeding speed change knob to acquire a proper feeding speed.

Please refer to the chart below for the proper current of the saw spindle motor:

Please be aware that the current value displayed on the ammeter shall not exceed the value shown in this chart.

(5) This machine is equipped with auxiliary in-feed and out-feed tables, to help the transportation of work pieces. Please refer to the drawing below:

(6) This machine is equipped with the overload protection for the saw spindle motor. During operation, operators could read out the load of the saw spindle motor from the ammeter on the button panel.

If the lamp S1 on the ammeter lights, it means that the load is over the value S1. Then the feeding chains will slow down automatically to a preset low speed (This preset low speed is able to be adjusted by the Low speed adjusting knob on the button panel.). While the load of the saw spindle motor decreases, the feeding chains will speed up automatically. While the light S1 dies, the feeding chains will be restored automatically to the normal feed speed (The normal feed speed is able to be adjusted by the Normal speed adjusting knob on the button panel).

If the lamp S2 on the ammeter lights, this means that the saw spindle motor is overloaded and the current is over the rated current. Then the feeding chains will stop automatically.

NOTE:

The preset low speed value shall be smaller than 50% of the normal feed speed.

The current real feed speed is displayed on the feed speed displayer.

5-12. Fall down the feeding speed setting regulation
